Pinhole Camera

**INTRODUCTION**

This pinhole camera takes 5" by 7" black and white photos (12.7cm by 17.8cm). The design has no electronics or lenses. The design does require a small amount of aluminum foil for the pinhole.

**ASSEMBLY**

STEP 1: After printing all the parts, they should intuitively click, thread, and/or stick together.

STEP 2: Attach the aluminum foil and poke the pin hole. You will need aluminum foil, glue, and the part called PinholeCamera_Pinhole.

Cut a small section of foil that covers the entire center hole, and the outside indented ring. Lay down glue inside the indented ring, and attach the foil, making sure it is stretch out - reflective side facing out. Once the glue is dry, use a sharp object to cut excess aluminum foil by tracing the indented ring.

Thread the piece onto the main body, and poke a hole in the center of the foil with a pin or small object (with roughly a .5mm diameter)

STEP 3: Press magnets into the body of the camera, and into the pinhole cover to create a magnetic pinhole cover!

Assembly complete! :)

**USE**

STEP 1: Load photographic paper into the tray in a completely dark space. Slide the tray into the camera, and before leaving the dark space ensure the pinhole cover is on.

STEP 2: Go find a subject to take a picture of (architecture is especially cool). Remove the pinhole cover for 2-5 minutes. (Getting the exposure right will take some guess work). For reference I first exposed on a bright sunny day for 2 minutes, and it yielded the image below.

STEP 3: Go back to your dark space, remove the paper from the camera, and develop the images in a developer and stop solution. Use a red light to help with visibility. This will give you a photo positive - the photo will be inverted. To reinvert the image like the in the photo above, take a photo of the original and use software, or look up how to create a negative from a postive pinhole photo.

**MATERIALS**

Ilford Multigrade V RC Deluxe Glossy Surface Black & White Photo Paper: This photographic paper has worked really well! It is a reasonable size - 5" by 7", and has held up great. This is the only paper I have tested in the camera.

60pcs Small Magnets: Used for the magnetic lens cover.

Aluminum Foil: The design does require aluminum foil like this for the pinhole.

Gorilla Super Glue: Glue is used to attach the aluminum foil to the print. This is the glue I used.

Pin: a pin or similar small object is required for creating the pinhole. 

Developer and Stop Solutions: You will need a developer and stop solution. I made my own using this video; however, I recommend just buying these solutions (handle them with care). The quality of the DIY solutions definitely shows.  

Additional Fun Item(s):

UV Flashlight Black Light: When developing and loading the paper, you might find it useful to have a red light (which won't affect the paper).
